RtlGUIDFromString returning STATUS_WAIT_1

NTDEV
1

Hi,

I am getting following error “STATUS_WAIT_1” while executing
RtlGUIDFromString from the DriverEntry of my volume filter driver. My
machine is a cluster node of win2k8 r2.
here is my code

ustrDiskSignature.Length = 72;
ustrDiskSignature.MaximumLength = 78;
ustrDiskSignature.Buffer is “71A27CDD-812A-11D0-BEC7-08002BE2092F”
GUID Guid;
Status = RtlGUIDFromString(&ustrDiskSignature, &Guid);

here the call RtlGUIDFromString is always getting failed with STATUS_WAIT_1.
Is it a problem to call this api to early in boot process.

Regards
Rohit Gauba

1 since you have a static string, call RtlInitUnicodeString instead of manually initializing each field
2 try surrounding the guid chars with { } s
